Belogradchik Fortress
Local name: Белоградчишка Крепост
The ancient fortress was built on the Bełogradczyce rocks in the 3rd century, i.e. during the reign of the Roman Empire. It is one of the best-preserved strongholds in Bulgaria and has been declared a monument of national importance.
During the construction of the fortress, 70 m high rocks were used, which are a natural protection, therefore the defensive walls were built only on the north-west and south-east sides. They are about 12 m high, and by the foundation their width exceeds 2 m. There are also three fortified courtyards in the fortress.
The stronghold was expanded in the 14th century during the reign of the Bulgarian Tsar Ivan Stracimir. It was rebuilt again in the 19th century. There were arrowslits in the walls at a height of 10 meters and 3 bastions were added. The fortress was used e.g. during the Serbo-Bulgarian war.
